ROBERT FRANCIS WALSH, OF PEORIA, ILLINOIS.

WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 480,913, dated August 16, 1892.

Application filed February 10, 1892- Serial No. 420,971. (No model.)

To all whom it may concern.-

Be itknown thatI, ROBERT FRANCIS WALSH, a citizen of the United States of America, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Water-Heaters, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to water-heaters, and belongs to the class in which water is made the vehicle fol-conveying and distributing the heat to distant compartments.

.The object of my invention is to provide a safe, clean, and economical means for heating railway-coaches; and it consists in the means of utilizing the heated products of combustion as they pass from the furnace and hues of a locomotive-boiler to the smoke-stack for the purpose of heating water with which to heat the coaches.

It further consists in jacketing the smokestack and combining it with the other parts, so that the water mayreceive additional heat while on its way to the coach-pipes.

It further consists in providing means to keep the water in circulation after the furnace has been fired but before the coaches have been connected; and it further consists of the combination and arrangement of the several parts for accomplishing the end desired.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a plan view showing the tender and a portion of a locomotive-boiler with my improvements attached. Fig. 2 is a front elevation of a locomotive-boiler, the end being removed to show my improvements in position. Figs. 3 and 4 are side elevations of a part of the boiler and tender, a portion of each being broken awayto show my improvements connected therewith.

Like letters of reference indicate corresponding parts in the several views.

A indicates the front part of an ordinary locomotive-boiler, the smoke-stack B being made double and the intervening space being filled with water. Inside the boiler and in front of the fines I locate a water-box O and connect the same with the water-jacket of the smoke-stack by means of a pipe D. The water in the box 0 is heated by the hot vapors as they issue from the fiues after they have served the usual purpose of gen eratlng steam for the engine. The water jacket of the smoke-stack B is connected with the trainpipe by means of a pipe E, (seeFigs. 1 and 2,) this pipe passing down and along the s1de of the boiler to the tender, where it connects with the train-pipe E by means of a hose or other suitable coupling and the water 1s thus passed from the boiler to the coaches or the tender, as occasion may require. If to the coaches, it passes through the pipes E upon one side and is returned by way of pipes E on the opposite side, entering the boiler at F and connecting with the water-box C at F. (See Figs. 2 and 3.) A coil of pipe 1s located in the tender and connected w1th the train-pipes E E at h it. Each of the pipes are provided at the point h h with cocks at n. The purpose for which this 0011 of pipe and the cooks are used is that when the tender is disconnected from the train the cooks 'n are turned so as to prevent the water from wasting and to compel it to circulate through the coil G on the turning of cocks 'n. This allows the water to circulate in the coil and to be cooled sufficiently to prevent its being turned into steam. When the coaches are connected, the position of these cocks Will be reversedand the water passed through the coach-pipes without entering the coil G in the tender.

The water-box O is provided with a series of tubes or fiues 7", which pass through the water and give a greater heating-surface and at the same time permits the smoke and other products of combustion to pass readily off to the smoke-stack.

The pipes L and M are those ordinarily used to convey live steam from the boiler to the cylinders, and the box Q and exhaust P are the same as those usually found in locomo- 'tives and are only introduced here to better illustrate the location and arrangement of my improvements.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The water-box 0, located in front of the boiler-flues, a jacketed smoke-stack over said box, and a pipe connecting the box and jackthrough the coil, substantially as described, eted smoke-stack, in combination with the and for the purpose set forth. 10 pipe E, leading from the smoke-stack to the In testimony whereof I affix my signature in tender, and the pipes E E leading to the presence of two witnesses.
